CORRUGATED-BOARD CONTAINER AND BLANK THEREFOR.

Application filed June 19, 1922. Serial No. 569,354.

To all whom it may concern:

Be it known that I, CHARLES H. CRowELL, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have made a certain new and useful Invention Relating to Corrugated-Board Containers and Blanks Therefor, of which the following is a specification, taken in connection with the accompanying drawing.

This invention relates especially to shipping containers made of corrugated paper board in which the body of the container may advantageously comprise a three or four sided blank having transverse creases between the sides and preferably having its edges rabbeted or stepped so as to form a projecting edge flange which comprises the outer facing of the paper board. This stepped edge may be greatly reenforced by pasting thereon a seam or edge reenforcing tape of gummed cloth or paper which engages the inner facing of the corrugated board and also adhesively engages the cut or rabbeted edge and the projecting edge flange so as to greatly strengthen th1s projecting flange against splitting action in case the cooperating member of the container is forced out against it. The body blank may have secured thereto one or more free sealing flaps or tapes preferably having corner folding notches so that after the cooperating blanks or members of the container are assembled and glued or secured in place, if desired, these'sealing flaps may be pasted over the same to securely and strongly hold them in place and tightly close the container.

In the accompanying drawing which shows in a somewhat diagrammatic way several illustrative embodiments of the invention:

Fig. 1 is a perspective view of an illustrative container.

Fig. 2 is a plan view of a blank therefor.

Fig. 3 is an enlarged sectional detail showing the form of edge joint and sealing members.

Fig. 4 is a similar sectional view where.

tainers may be made of ordinary or crosscorrugated paper board and of course the size and proportions of the blanks are made so as to suit the particular size and character of container desired. As shown in Figs. 1 and 2 the container may be formed of a four-sided body blank having the transverse creases 6, 7, 8 formed therein between the adjacent sides and it is usually desirable to have the corrugations run vertically or transversely of the length of this blank where single corrugated board is used for making the same. As shown more in detail in Fig. 3, the edge portion of the blank may advantageously be given a rabbeted or stepped form so as to leave a projecting edge flange 18 comprising the outer facing of the corrugated board to which the usual corrugated spacing member 17 is adhesively secured. These edge portions may be greatly strengthened and reenforced by adhesively securing thereto seam reenforcing tape such as 15 which may be strong gummed paper tape which is pasted or glued to the inner facing of the side 2 of the container and then across the corrugated spacing member to form the portion 14 of this reenforcing tape which may also form the securing reenforcing member 13 strongly secured to the outer facing of the corrugated board the edge 11 of the tape preferably substantially coinciding with the upper or free edge of this flange 18. Both the upper and lower edges 11, 12 of the blank may be similarly provided with such a seam reenforcing tape and as shown in Fig. 3, any outward pressure on this rabbeted edge of the body blank which might be exerted by the cooperating top or other container member is largely or wholly borne by this strong tape which to a considerable extent transmits such outward pressure to the inner facing of the corrugated board instead of forcing or splitting away the outer facing' or. edge flange 18. It is also advantageous to form the body blank in the factory where it is shaped and creased with attached sealing flaps such as 5, 5 which are glued to the outer facing throughout the top and bottom edges of the blank at least so that when the other container members are put in place these sealing flaps may be brought down upon the top member, for instance, and successively sealed in place which strongly secures the top member in position and also forms a tight closure especially where the corner folding 'eousl to stren then a rabbeted ed 'e or b in "projecting flange in cross-corrugated paper board having two transversely arranged corrugated paper spacing members 17 adhesively secured to the facing members such as 19, 22. One orboth ofthese rabbeted edges may be provided with similar seam reenforcing tape such as the gummed paper tape 11, 18, 14, 1'5 adhesively secured to the corresponding sides and edges of the rabbeted blank or container member so as to similarly prevent splitting when the adjacent cooperating container member is forced outward with respect thereto.

Tt-is not of course necessary to have foursided blanks 'forthese containers in all cases and Figs. 5 and 6 show three-sided container blanks which may be interconnected so as to'form asix-sided container in the manner shown in Fig. 6. One of these blanks forms thesides or faces 23, 24, 25 of the container and another somewhat similar three-sided blank of the container forms the sides 28, 24 and 25, atleast one of the blanks having such sealing flaps as 5, 5, 26 and '29 to be ,Pasted or secured to the adjacent edges of the otherblank and hold all of the parts securely together in assembled position. All of the rabbeted edge flaps or portions of the blank may be strengthened by seam reen forcing tape such as 27 which may be glued 'orpasted around the same as indicatedin Fig. '5 so as to greatly strengthen these rabbeted edges against splitting.

"This invention has been described in connection with a number of illustrative embodiments, forms, portions, parts, materials, arrangements and methods of manufa'c'ture' and'use, to the details of which disclosure the invention is not of course to be limited,-sinc'e what is claimed as new and what is desired to be secured by Letters iPat'ent is set forth in the appended claims.

I "claimlfThe corrugated paper board shipping container comprising a four sided straight strip bodyblank of corrugated paper board having the corrugations arranged transversely of the length of the blank and formed with transverse folding creases between the adjacent sides, said blank being formed with stepped edges in which the outer faci'ngof'the corrugated board constitutes a pro ecting edge "flange, seam reenforcing t'ape adheslvely secured to said -said top and bottom members to secure them in place and form a substantially tight closure for the container.

2. The corrugated paper board shipping container comprising a four sided straight strip body blank of corrugated paper board and formed with transverse folding creases between the adjacent sides, said blank being formed with stepped edges in which the outer facing of the corrugated boar'd'constitutes a projecting edge flange, seam reenforcing tape adhesively secured to said stepped edges to strengthen the same and minimize the splitting ofi of this flange under outward pressure, top and bottom members of corrugated paper board, said body blank having free sealing-flaps pasted to the longitudinal edges thereof to be adhesively secured to the adjacent portions of said top and bottom members to secure them in place and form a substantially tight closure for the container.

3. The corrugated paper board shipping container comprising a multiple sided straight strip body blank of corrugated paper board, said blank being formed with stepped edges in which the outer portion of'the corrugated board constitutes a projecting edge flange, seam reenforcing tape 'adhesively secured to the inner facing of the corrugated board. and along the adjacent stepped edge to strength'enthefsame under outward pressure and connected-container members of corrugated paperboard sealing tape being adhesively secured to the adjacent portions of said body blank and connected container members to secure them in place and form a substantially tight closure for the container.

5. The shipping container comprising a multiple side straight strip container blank formed of corrugated paper board, and

formed with folding creases and with stepped edges and seam reenforcing tape adhesively secured to the corrugated board adjacent said stepped edges to strengthen the projecting edge portions.

6. The shipping container comprising a multiple side container blank formed of corrugated paper board, and formed with stepped edges and seam reenforcing tape adhesively secured to the corrugated board adjacent said stepped edges to strengthen the projecting edge portions.
